Subject: [PATCH 2/6] export: add EACCES to the list of known path_lookup_error() errors.
Date: Mon, 23 Oct 2023 12:58:32 +1100	[thread overview]
Message-ID: <20231023021052.5258-3-neilb@suse.de> (raw)
In-Reply-To: <20231023021052.5258-1-neilb@suse.de>

If a 'stat' results in EACCES (for root), then it is likely a permanent
problem.  One possible cause is a 'fuser' filesystem which only gives
any access to the user which mounted it.

So it is reasonable for EACCES to be a "path lookup error"
